We don't really support devices changing capabilities at runtime. The kernel has no ability to tell us when this happens on an already-opened device and the few devices that can literally change physical capabilities (e.g. the wiimote) open up extra kernel devices instead of modifying the existing one. Thus, we don't need to notify about devices changing capabilities. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
